ANTISMUT-WEB FOR PRINTED SHEETS.

Patented Oct. 12, 1915.

Application filed January 7, 1913. Serial No. 740,619.

To all whom it may concur Be it known that I, (humus I CorrnnLL, a citizen of the United States, and resident of Westerly, in the county of lVashington and State of Rhode Island, have invented a new and useful Improvement in Antisinut- \Vebs "for Printed Sheets, of which the following is a specification.

In winding up printed sheets in an antisniut web roll of ordinary form, is very difficult, if not impossible, to keep the roll from becoming distorted because of its liability to cone, due to the necessary extension of the sides of the roll beyond the side edges of the printed sheets for protecting them. The great pressure exerted on the printed sheets by the Web in this method of slip sheeting is also undesirable. The edges of the printed sheets are alsoleft unprotected from dust and dirt.

My present invention has for its object, to provide means on the anti-smut webfor maintaining the roll in its cylindrical "form, reducing the pressure of the web on the printed sheets and protecting the printed sheets from dust and dirt.

Practical embodiments of my invention are represented in the accompanying drawings, in Which Figure 1 is a perspective view showing one form of my improved anti-smut web in connection with its supply and winding rolls, a printed sheet and means for feeding the .sheet onto the Web Fig. 2 is a detail section taken in the plane of the line AA of Fig. 1, Figs. 3, L, 5, 6, 7, 8 and 9 are similar sections 'showing various other forms of antismut webs.

The printed sheet is denoted by 1.

The anti-smut Web is denoted by 2, the supply roll by 3 and the Winding roll by The anti smut web is shown as passing around a guide roll 5 to present a surface for Guides 6 of nism are also shown.

In Figs. land 2 the anti-smut web is shown as having its side edges 7 and 8 folded over and permanently united to the web.

In Fig. 3 two strips 9 and 10 are'shown embossing the web.

as permanently united to the Web along'its side edges.

non. i

In Fig. 4 the web itself is thickened along its side edges as shown at 11 and 12.

In Fig. 5 the side edges of the Web are raised, as shown at l3, l-l, as by embossing.

In Fig. 6 the web is shown as being suitable for receiving a plurality of sheets side by side thereon, the side edges of the'Web being folded over and permanently united to the web, as shown at 15 and 16, and an intermediate strip 17 being shown as permanently united to the web.

In Fig. 7 the web is shown as being provided with the two side strips 18, 1.9, and the intermediate strip 20, all permanently united to the web.

In Fig. 8 the web is shown as having the two side strips 21, 22, and intermediatestrip 23, formed integral with the web.

In Fig. 9 the web is shown as provided with two raised side portions 24:, 25, and an intermediate raised portion 26 formed by In the several forms herein shown, the web is provided with means for preventing the roll from being distorted and from-reducing the pressure upon the printed sheets. Each web is also provided with one or.-m01'e do pressed surfaces for receiving the printed sheets and in certain of the forms the Web is provided with thickened portions arranged longitudinally of the web for receiving the printed sheets between them.

It is to be understood that any means may be employed for rolling the smut-Web and the printed sheets together. I

The construction of the web is such that the roll will be maintained in its cylindrical condition irrespec'tixe of the size of the roll and the printed sheets also being protected from injury. It will also be seen that the Web is provided with means for preventing the access of dust or dirt to the edges of the printed sheets while wrapped up in the roll.

While I have shown several embodiments of my invention in the accompanying drawings', it is evident that there are many other we. We?

venti'on; hence I donot wish to limit myself to the embodiments herein shown and described, but

What I claim is I. An anti-smut web adapted to be wound in a roll with printed sheets and having longitudinally arranged thickened edge and intermediate portions having between them depressed surfaces for receiving the sheets.

2. An anti-smut web adapted to be wound in a roll with printed sheets and having folded over edges and a longitudinally thickened portion having between them depressed surfaces for receiving the sheets.

3. An anti-smut web adapted to be wound its side edges folded ever and permanently united to the web leaving a longitudinally arranged intermediate portion, for receiving the sheets.

4. An anti-smut web adapted to be Wound in a roll with printed sheets and having presence of two witnesses, this twenty third day of December 1912.
